3 Wood"energy"and"biomass"H"definiAons" Biomass constitutes the largest source of renewable energies in the EU (66%), and In mostly 89% wood 11% plant and animal biomass, Waste, landfill gas etc Wood is the major source for biomass (89%). Thus, wood is the major source for all renewable energy generation in the EU = 59% Source: UN Economic Commission for Europe 2008 Out mostly heat
